Original prompt

Port all changes from PR #256 (which was merged to main by mistake) onto the branch cursor/astro-ssg-rework-280b. Ensure every file, workflow, and migration documented and coded in #256 is applied/adapted to cursor/astro-ssg-rework-280b. This covers Astro migration, GitHub Actions improvements, remote data contract, and associated documentation/workflow/config changes, as well as bugfixes and UX tweaks. Exclude any changes that do not apply due to cursor/astro-ssg-rework-280b already having more recent or conflicting code, but provide a detailed summary of any skipped/conflict areas. The goal is to bring cursor/astro-ssg-rework-280b fully up to the improved, unblocked state achieved by #256.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: Agent tread; https://github.com/SillyLittleTech/Portf/tasks/4fc4991e-87f6-43cc-b45d-5531e0075195?session_id=e0e67947-5d7c-4bdd-9aba-1aa674165a7b

Inadvertantly targeted main, which does not exist many of the fixes this session is working on. We need these changes to target cursor/astro-ssg-rework-280b, please make an agent session or PR that will resolve these issues into the correct branch.

Assistant: The changes from PR #256 ("Resolve PR review feedback and unblock GitHub Pages preview deploy") in SillyLittleTech/Portf were merged into the main branch—however, you want these fixes applied to cursor/astro-ssg-rework-280b.

What needs to be done:

• Reapply the full set of changes from Resolve PR review feedback and unblock GitHub Pages preview deploy #256 onto the cursor/astro-ssg-rework-280b branch.
• This can be done by opening a PR that ports/adapts these edits to the correct branch.

Next step

I will create an agent PR that applies these changes on top of the cursor/astro-ssg-rework-280b branch to resolve all issues and ensure the branch has the same improvements/fixes as intended by #256.

Would you like to port the changes exactly as in PR #256, or do you want to adapt/exclude any specific files or changes for cursor/astro-ssg-rework-280b?

Let me know before I proceed—otherwise, I'll start porting the full PR as-is.

User: Do it

Assistant: I am preparing a pull request that will port all changes from PR #256 onto the cursor/astro-ssg-rework-280b branch, adapting as needed and providing a summary of any conflicts or skipped areas. The PR will ensure that branch is fully updated with the improvements, fixes, and migrations originally intended by #256. I will report back once the PR has been created or if any issues arise.
